An autonomous integration model based on flexible service for China Railway Heterogeneous Information System

New period information system should have an ideal on-line abilities and rapid response ability in order to satisfy various service demands. The existing information systems of China railway have been proved that its systems' limitations have affect transport and operation abilities rising, the system abilities and properties should be improved. Aiming at this problem, in this paper, a novel heterogeneous information integration method is proposed to improve system's multi-level abilities without abandoning the existing information systems, the novel model provides a heterogeneous information integrated method. The novel architecture is a succession and expansion of ADS and its technologies, in new system architecture, Information Flexibility Descending Field (IFDF) model is designed to support service-based integration and autonomous service, through that various individual information resource are integrated together. In order to implement autonomous service navigation, paper implements node communication Mechanism, finally China Railway Heterogeneous Information Integrating System (CRHIS) model is given out based on flexible service, Experimental result demonstrates that this service-based model has a better responsive ability than old server-based system model, at the same time system architecture implemented by IFDF assures that new system has a better on-line properties.
